Description

Technical Field

[0001] This utility model relates to the field of electronic equipment protection technology, and more specifically, to a composite structure device for waterproof sealing and quick locking of extravehicular equipment. Background Technology

[0002] With the widespread application of extravehicular equipment, its working environment is often exposed to external factors such as rain, moisture, and dust, which places high demands on the waterproof and sealing performance of the equipment.

[0003] Currently, the waterproof sealing of external control cabinets mainly relies on rubber sealing rings or silicone gaskets, achieving a seal through compression. However, after long-term use, these structures are prone to deformation or cracking of the sealing rings due to material fatigue, temperature changes, or mechanical stress, thus reducing the sealing effect. Furthermore, existing locking structures mostly use distributed locking components such as bolts, clips, or knobs, requiring the sequential operation of multiple locks to complete the fixation. This is not only time-consuming and labor-intensive but may also lead to uneven sealing due to improper tightening sequence, further increasing the risk of leakage. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a composite structure device for waterproof sealing and quick locking of extravehicular equipment, which has the advantages of improving sealing and facilitating quick locking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite structure device for waterproof sealing and quick locking of extravehicular equipment, comprising a cabinet and a door. The cabinet includes a shell, and a support base is provided below the shell. The door includes a door panel. Two platforms are welded to the left end of the shell, and a circular shaft is welded between the inner sides of the two platforms. The door panel is movably sleeved on the outer side of the circular shaft. A sealing strip located inside the circular shaft is glued to the outer side of the shell, and the sealing strip is tightly fitted to the outer wall. A sealing plate is glued to the front right end of the shell, and a sealing groove is provided on the inner side of the door panel, which is adapted to the sealing plate.

[0006] As a preferred embodiment of this utility model, a rectangular plate is welded to the right side of the housing, a slot is provided on the front side of the rectangular plate, and a groove extending to the outside of the rectangular plate is provided on the inner side of the slot. A protruding plate is welded to the right side of the door panel, and an insert plate extending into the slot is welded to the inner side of the protruding plate. A movable groove is provided inside the insert plate, and an arc panel is slidably installed inside the movable groove. The front end of the arc panel extends into the groove, and a telescopic spring is elastically installed between the inner side of the arc panel and the inner side of the movable groove. A drainage groove is provided on the inner side of the bottom of the door panel.

[0007] As a preferred technical solution of this utility model, the movable groove is provided with sliding grooves on both sides, and connecting blocks are welded to both ends of the bottom sides of the arc panel. A roller is rotatably installed between the inner sides of the two connecting blocks, and the outer side of the roller is in contact with the inner wall of the sliding groove.

[0008] As a preferred technical solution of this utility model, the sealing strip is made of EPDM rubber and its cross-section has a hollow multi-lip structure.

[0009] As a preferred embodiment of this utility model, the contact surface between the insert plate and the slot is provided with a PTFE wear-resistant coating; the pressure-bearing surface of the arc panel is an involute curved surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model effectively solves the problem of easy aging and failure of traditional sealing structures through multiple sealing designs and the application of weather-resistant materials; the multi-lip sealing strip of EPDM rubber is tightly fitted to the door panel, and its hollow cross-section structure can generate adaptive deformation under pressure to compensate for gaps caused by mechanical stress or temperature changes, ensuring long-term sealing stability; the addition of a sealing plate and a sealing groove to form a second waterproof barrier can still prevent water from seeping in even if the main sealing strip fails partially; in addition, the drainage groove designed at the bottom can quickly drain accumulated water and prevent liquid from stagnating and corroding the sealing surface.

[0012] 2. This utility model completely changes the cumbersome operation of traditional multi-step locking by linking the spring-driven buckle mechanism with the sealing system. Through the cooperation of the insert plate and the slot, combined with the automatic locking of the arc panel under the action of the telescopic spring, the user only needs to press and push to complete the locking or unlocking. During the locking process, the involute curved surface of the arc panel generates progressive pressure when it contacts the rectangular plate, forcing the insert plate to be fully inserted. Then, the telescopic spring releases its elasticity to push the arc panel into the slot. At this time, the pressure of the door panel on the sealing strip is evenly distributed, avoiding the problem of uneven sealing caused by manual tightening. In addition, the application of PTFE wear-resistant coating reduces the frictional wear between the insert plate and the slot, and the rolling cooperation between the roller and the slide further reduces mechanical resistance, so that the locking mechanism can still remain smooth after frequent use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 7 As shown, this utility model provides a composite structure device for waterproof sealing and quick locking of extravehicular equipment, including a cabinet 1 and a door 2. The cabinet 1 includes a shell 11, and a support base 12 is provided below the shell 11. The door 2 includes a door panel 201. Two platforms 13 are welded to the left end of the shell 11. A round shaft 14 is welded between the inner sides of the two platforms 13. The door panel 201 is movably sleeved on the outer side of the round shaft 14. A sealing strip 15 located inside the round shaft 14 is glued to the outer side of the shell 11. The sealing strip 15 is tightly fitted to the outer wall of the shell 21. A sealing plate 16 is glued to the front right end of the shell 11. A sealing groove 202 is opened on the inner side of the door panel 201. The sealing groove 202 is adapted to the sealing plate 16. The sealing strip 15 is made of EPDM rubber and its cross-section is a hollow multi-lip structure.

[0023] The user holds the handle of the door 2 and pulls the door panel 201 outward, causing it to rotate around the circular axis 14. The door panel 201 gradually separates from the housing 11. During the opening process, the tight fit between the sealing strip 15 and the inner wall of the door panel 201 gradually loosens, and the sealing plate 16 exits from the sealing groove 202, releasing the second seal. The user pushes the door panel 201 towards the housing 11, causing it to rotate around the circular axis 14 and close. The inner wall of the door panel 201 first contacts and compresses the sealing strip 15, forming the first seal. As the door panel 201 continues to close, the sealing plate 16 aligns with and inserts into the sealing groove 202, forming the second seal. After closing, the sealing strip 15 adheres tightly to the inner wall of the door panel 201 due to its elastic restoring force, ensuring that the annular sealing surface has no gaps. The insertion and cooperation between the sealing plate 16 and the sealing groove 202 further prevents external moisture or dust from entering, and the double sealing structure enhances the overall protective performance.

[0024] The multi-layered sealing design and the application of weather-resistant materials effectively solve the problem of easy aging and failure of traditional sealing structures. The EPDM rubber multi-lip sealing strip 15 is tightly fitted to the door panel 201. Its hollow cross-section structure can generate adaptive deformation under pressure, compensate for gaps caused by mechanical stress or temperature changes, and ensure long-term sealing stability. The added sealing plate 16 and the sealing groove 202 are interlocked to form a second waterproof barrier, which can still prevent water from seeping in even if the main sealing strip fails partially. In addition, the drainage groove 203 designed at the bottom can quickly drain accumulated water and prevent liquid from stagnating and corroding the sealing surface.

[0025] A rectangular plate 17 is welded to the right side of the housing 11. A slot 18 is provided on the front side of the rectangular plate 17. A groove 19 extending to the outside of the rectangular plate 17 is provided on the inner side of the slot 18. A protruding plate 204 is welded to the right side of the door panel 201. An insert plate 205 extending into the slot 18 is welded to the inner side of the protruding plate 204. A movable groove 206 is provided inside the insert plate 205. An arc panel 207 is slidably installed inside the movable groove 206. The front end of the arc panel 207 extends into the groove 19. The inner side of the arc panel 207... A telescopic spring 208 is elastically installed between the movable groove 206 and the inner side of the door panel 201. A drainage groove 203 is provided on the bottom inner side of the door panel 201. Slide grooves 209 are provided on both sides of the movable groove 206. Connecting blocks 210 are welded to both ends of the bottom sides of the arc panel 207. A roller 211 is rotatably installed between the inner sides of the two connecting blocks 210. The outer side of the roller 211 is in contact with the inner wall of the slide groove 209. The contact surface between the insert plate 205 and the slot 18 is provided with a PTFE wear-resistant coating. The pressure surface of the arc panel 207 is an involute curved surface.

[0026] When the door 2 needs to be opened, simply hold the handle with one hand and press the curved panel 207. This causes the curved panel 207 to retract into the movable groove 206 under pressure, compressing the telescopic spring 208 and causing it to deform. Once the curved panel 207 is fully retracted into the movable groove 206, pull the handle to remove the insert plate 205 from the slot 18. When locking is required, simply insert the insert plate 205 into the slot 18. The inclined surface of the curved panel 207 first contacts the surface of the rectangular plate 17, causing the curved panel 207 to retract into the movable groove 206 under pressure, compressing the telescopic spring 208. Once the insert plate 205 is fully inserted into the slot 18, the curved panel 207 is positioned inside the slot 19. The telescopic spring 208 releases its elastic potential energy, pushing the curved panel 207 upward, thus fixing the curved panel 207 via the plane on the other side.

[0027] By linking the spring-driven buckle mechanism with the sealing system, the cumbersome operation of traditional multi-step locking is completely changed. Through the cooperation between the insert plate 205 and the slot 18, combined with the automatic engagement of the arc panel 207 under the action of the telescopic spring 208, the user only needs to press and push to complete the locking or unlocking. During the locking process, the involute curved surface of the arc panel 207 generates progressive pressure when it contacts the rectangular plate 17, forcing the insert plate 205 to be fully inserted. Then, the telescopic spring 208 releases its elasticity to push the arc panel 207 into the slot 19. At this time, the pressing force of the door panel 201 on the sealing strip 15 is evenly distributed, avoiding the problem of uneven sealing caused by manual tightening. In addition, the application of PTFE wear-resistant coating reduces the frictional wear between the insert plate 205 and the slot 18, and the rolling cooperation between the roller 211 and the slide 209 further reduces mechanical resistance, so that the locking mechanism can still remain smooth after frequent use.

[0028] Working principle and usage process of this utility model:

[0029] The user holds the handle of the door 2 and pulls the door panel 201 outward, causing it to rotate around the circular axis 14. The door panel 201 gradually separates from the housing 11. During the opening process, the tight fit between the sealing strip 15 and the inner wall of the door panel 201 gradually loosens, and the sealing plate 16 exits from the sealing groove 202, releasing the second seal. The user pushes the door panel 201 towards the housing 11, causing it to rotate around the circular axis 14 and close. The inner wall of the door panel 201 first contacts and compresses the sealing strip 15, forming the first seal. As the door panel 201 continues to close, the sealing plate 16 aligns with and inserts into the sealing groove 202, forming the second seal. After closing, the sealing strip 15 adheres tightly to the inner wall of the door panel 201 due to its elastic restoring force, ensuring that the annular sealing surface has no gaps. The insertion and cooperation between the sealing plate 16 and the sealing groove 202 further prevents external moisture or dust from entering, and the double sealing structure enhances the overall protective performance.

[0030] When the door 2 needs to be opened, simply hold the handle with one hand and press the curved panel 207. This causes the curved panel 207 to retract into the movable groove 206 under pressure, compressing the telescopic spring 208 and causing it to deform. Once the curved panel 207 is fully retracted into the movable groove 206, pull the handle to remove the insert plate 205 from the slot 18. When locking is required, simply insert the insert plate 205 into the slot 18. The inclined surface of the curved panel 207 first contacts the surface of the rectangular plate 17, causing the curved panel 207 to retract into the movable groove 206 under pressure, compressing the telescopic spring 208. Once the insert plate 205 is fully inserted into the slot 18, the curved panel 207 is positioned inside the slot 19. The telescopic spring 208 releases its elastic potential energy, pushing the curved panel 207 upward, thus fixing the curved panel 207 via the plane on the other side.
